What are probiotic drinks and how do they help?

Probiotics can come in food, homemade drinks and supplements. There are hundreds of bacteria classified as probiotics, but most come from two main species: Lactobacillus and Bifidobacterium. Within each of these are various strains. Probiotics are considered “good bacteria.” They help keep us healthy by interacting with the intestinal lining to protect the body from harmful invaders. They help the immune system function properly, which means better ability both to fight infections and to dampen chronic inflammation.
